Purge formulas from Brewfile
Purge formulas from Brewfile

It looks like the brewfile used to track explicitly installed
dependencies from Homebrew has accumulated a lot of cruft.

I think older versions of `brew bundle` included all installed formulas
rather than only user-installed formulas. As this bundle has been used
to bootstrap new machines over time, these legacy formulas were marked
as user-installed.

There was a ton of gunk in here that needed to be cleaned out.

I ended up nuking all installed formulas and reinstalling only these.
The Brewfile now correctly marks user-installed packages.
